Like the cup fills with water, SO WILL EARTH FILL WITH PEACE. THERE WILL BE NO ENMITY LEFT BETWEEN ANY PEOPLE. ALL HOSTILITY, FIGHTING, AND ENVY WILL DISAPPEAR. ...(Sahih Muslim, 1/136)

... In the same way that Almighty Allah began Islam with us, so He will bring it to an end with him [Hazrat Mahdi (as)]. In the same way that they were freed from polytheism and enmity andTHEIR HEARTS WERE FILLED WITH FRIENDSHIP AND LOVE THROUGH ME, SO IT WILL BE AGAIN WITH THE COMING OF HAZRAT MAHDI (AS). (Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir az-Zaman, p. 20)

... In his [Hazrat Mahdi’s (as)] time, THE GOODNESS OF GOOD MEN WILL GROW, AND EVEN THE BAD WILL BE TREATED WELL.(Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir az-Zaman, p. 17)

The world filled with oppression and tyranny WILL OVERFLOW WITH JUSTICE AFTER HE [HAZRAT MAHDI (AS)] COMES.(Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar, p. 20)

[In Hazrat Mahdi’s (as) time] ALL ENMITIES, GRUDGE DISAPPEAR, the poison of each poisonous animal is drawn. Furthermore, a child puts his hand in the mouth of a snake but that snake does not give harm to it. A wolf becomes like a shepherd dog among a sheep herd. THE EARTH IS FILLED WITH PEACE AND SECURITY as if a bowl is filled with water. A single word (the word of tawhid) remains and people worship only Allah. WARRIORS LEAVE THEIR LOAD (THAT IS THEIR ARMS, WEAPONS ETC.)(Al-Sharani, Mukhtasar Tazkirah al-Qurtubi, pp. 496-497)

[In the age of Hazrat Mahdi (as)] THE SHEEP WILL GRAZE WITH THE WOLF AND CHILDREN WILL PLAY WITH SNAKES AND SCORPIONS BUT WILL COME TO NO HARM....(Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-Muntadhar, p. 43)

Hazrat Mahdi (as) is one of my people, andHE WILL FILL THE EARTH WITH TRUTH AND JUSTICE, just as it is now filled with cruelty and torture. (Sunan Abu Dawud, 5/93)

This (Amr) [Hazrat Mahdi (as)] WILL FILL THE EARTH WITH JUSTICE, just as people previously filled it with cruelty. (Sunan Ibn Majah, 10/348)

Hear the glad tidings of Hazrat Mahdi (as). He is one from Quraysh and from my Ahl al-Bayt. He will appear at a time when people are in disputes and social upheaval. HE [HAZRAT MAHDI (AS)] WILL FILL THE EARTH WITH JUSTICE AND COMPASSION, WHEN BEFORE HIM IT WAS FILLED WITH CRUELTY AND OPPRESSION. (Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir az-Zaman, p. 13)
